Oregon Museum of Science, Industry attempts world's largest baking soda volcano

When you were in elementary school, chances are you built a baking soda volcano.

But it was probably nothing like the one being built at the Oregon Museum of Science and Industry (OMSI).

It didn’t look like much Friday, but the pipes, scaffolding and tarps will eventually come together to form what OMSI hopes will be the world’s largest baking soda volcano.

It stands 34 feet tall, which is almost twice as tall as your typical giraffe.

But in order to get the world record, OMSI has to get a big explosion, too – more than four feet – so it is packing in 66 gallons of vinegar and 50 gallons of a baking soda-water mixture.

“It’s definitely going to be a fantastic explosion, and hopefully not too big of a mess, but we’ve never done this before,” said Sonali Shivdasani, event planner at OMSI.

It’s all part of the featured Pompeii exhibit at the museum.

The actual explosion will start on Sunday at 3 p.m. in front of the museum. KATU will have a crew there. But the museum plans to do it again on Wednesday at its “After Dark Event.”
